What is the maximum duration of symptom onset that requires transport to an approved stroke center?

Transporting a patient to an approved stroke center is critical when stroke symptoms are recognized. The maximum duration of symptom onset that typically justifies transport to a stroke center is 6 hours. This timeframe is based on the concept that many stroke treatments, especially thrombolytic therapy, are most effective within the initial hours after symptoms begin. Beyond 6 hours, the risks of treatment may outweigh the benefits, and many therapeutic options may no longer be viable.

The 6-hour window is also backed by clinical guidelines and evidence indicating that earlier interventions can lead to better outcomes, such as improved chances of recovery and reduced side effects. Once the 6-hour mark passes, decision-making becomes more complex, and many stroke centers may not administer certain treatments due to concerns about efficacy and safety. Therefore, understanding this timeframe is essential for AEMTs to ensure timely and appropriate patient care.
